3 Claims.

The present invention relates to new and useful improvements in boats and has for its primary for actuating said runners to operative and in operative position.

Still another very important object of the invention is to provide a boat of the aforementioned character embodying novel means for yieldingly mounting the hull on the runners thereby permitting the vehicle to travel over rough ice without being damaged thereby or causn discomfort to the occupants thereof. v

Other objects of the invention are to provide a boat of the character described which will be comparatively durable, highly pact and which simple in construction, strong, ecient and reliable in use, commay be produced at low cost.

All of the foregoing and still further objects and advantages of the invention will become apparent from a study of the following specification,

taken in connection with the accompanying drawings wherein like characters of reference designate corresponding parts throughout the several views, and wherein: v

Figure i is a view in side elevation of a boat embodying the present invention,.the major portion thereof being broken away in vertical'longitudinal section.

Figure 2 is a cross sectionahview, taken substantially on the line 2 2 of Fig. `1.

Figure 3 is a View in vertical section through one of the runners and the resilient mount therefor, taken substantially on the line 3 3 of Fig. 4.

Figure e is a View in side elevation of the por tion ci the invention shown in Fig. 3.

Figure 5 is a detail view in perspective, showing the pin and slot connectionbetween thehand lever and one of the cam operating bars.

Figure 6 is a cross sectional view, taken substantially on the line 6-5 of Fig. 1.

Figure 7 is an elevational view of a modied form of cam operating means.

Figure S is a top plan view of one of the runner supports.

Referring now to the drawings in detaiLit will be seen that the embodiment of the invention which has been the type shown the drawings.

illustrated comprises a hull I of to advantage in Figs. 1 and 2 of Rigidly secured, as at 2, to the bottom 3 adjacent each side of the hull I is a series of vertical guides 4 which communicate with openings in said bottom 3, said guides having suitable lubricating fittings 5 therein. Posts 6 are slidably mounted in the guides 4, said posts projecting downwardly through the openings provided therefor in the bottom 3 of the hull I and having xed on their lower end portions runners l.

' The runners 'I areof suitable resilient material and, as best seen in Fig. l of the'drawings, said runners conform substantially to the longitudinal 'curvature of the bottom 3 of the hull I.' The upwardly curved forward end portions of the run? ners 'l extend between pairs of guides 8, which are provided therefor beneath the bowofthe hull l. Extending* between each pair of guides tis a pair of rods or the like 9 (see Fig. 1) between which thev end portions of the runners i are operable. Stops iareprovided on theffor- Y ward ends of the runners I for preventing said runners from being withdrawn rearwardlyfrom between the elements 9. v Rising from the vertical posts 6 are stems AII having discs I2 slidably mounted on their upper portions. Depending from the discs i2 are sleeve bearings I3. Inner and outer coil springs I4 and I5, respectively, are provided beneath the discs I2. have their lower ends engaged on the upper ends of the posts 6 and the outer coil springs I5 rest on theV Vupper ends of the-guides il. Retaining nuts I6 for the discs I2 are threaded on the upper end portions ofthe stems Il. The posts E are provided with suitable packing rings I1 for preventing leakage therearound. Pairs of rollers I8, the purpose of which will. be presently set forth, are mounted on top of the discs I2.

, Mounted on the bottom 3 of the hull I on opposite sides of the guidesv t are pairs of substantially U-shaped inclined standards i9 comprising upstanding arms 2i) on their upper ends. EX- tending between the pairs of arms 2@ are pins 2l and journalled thereon are cams 22 in the form of rings which are operatively engaged with the rollers i8 on the discs I2. 'I'he upper portions of the cams 22 bend inwardly and merge, as at 23, and rising therefrom is an operating arm 24. The reference numeral 25 designates a` bar or rod which connects the cams 22 of each series for operation in unison. A transverse shaft 26 (see Fig. 2) is journalled for rocking movement in the rear portion of the hull I. Fixed on the end portions of the shaft 2@ are arms 2l. The rods 25 are operatively connected to the free The inner coil springs. i4, it will be noted,

end portionsI of the arms 2'I through the medium of links 28. Thus, the bars 25 on both sides of the hull I are connected for operation in unison. The reference numeral 29 designates a hand lever which is operatively connected, at an intermediate point, to one of the rods 25 through the medium of a pin and slot connection 30. This pin and slot connection is shown to advantage in Fig. of the drawings.

It is thought that the operation of the invention will be readily apparent from a consideration of the foregoing. When the boat is travel- 'ling on water the posts E are held in raised position by the coil springs I4 and I5 thereby holdingthe runners 'I in raised or inoperative position closely adjacent the bottom 3 of the hull, as shown in full lines in Fig. 1 of the drawings. However, when the vehicle is to travel over snow or ice the runners 'I are lowered to operative position, as suggested in broken lines in Fig. l of the drawings. This is accomplished by swinging the -hand lever 29 forwardly as seen in Fig. 1 of the drawings, thus rocking the cams 22 in a manner to force the discs I2 downwardly on the stems I I. When this occurs the inner springs I4 push the posts 6 downwardly in the guides 4 through the bottom 3 of the hull thereby lowering the runners 'i to operative position. With the runners 'I in operative position, the weight of the hull I is carried by the inner coil springs I4. It will thus be seen that a resilient mounting is had which will permit the vehicle to travel over rough ice or snow without being damaged from shock or vibration and with minimu-m discomfort to the occupants. When the hand lever 29 is swung in theopposite direction, or rearwardly, the cams 22 are actuated in a direction to permit the coil springs I 4 and I5, particularly the latter, to retract or raise the runners 1 to inoperative position again. The Vrudder is propelled by an air screw 3 I. An air rudder 32 is provided rearwardly of the screw 3I;

In the slight modification shown in Fig. 7 of the drawings, a hand wheel 33 is substituted for the lever 29. The hand wheel 33 is xed on a shaft 34 which is journalled horizontally on a Ysuitable support 35.

Also xed on the shaft 34 is a sprocket gear 35. A sprocketl chain 37 is Vtrained over' the sprocket gear 36 and is connected at its ends, as at 38, to thefadjacent rod 25. Thus, by rotating the hand wheel 33 the ad- Yjacent rod 25 is'shifted forwardly or rearwardly.

cations and changes in the details of construction may be resorted to which will fall within the scope of the invention as claimed.

What isl claimed is:

1. A boat of the class described comprising a hull including a bottom, vertical guides rising from the bottom, vertically movable posts slidably mounted in the guides and operable through the bottom of the hull, runners mounted on the lower ends of the posts beneath said bottom of the hull, pairs of standards mounted adjacent the guides, pairs of cams journalled between said pairs of standards, vertical stems rising from the posts, discs slidably mounted on the stems and engaged with the cams for downward actu'- ation thereby, coil springs yieldingly connecting the posts to the discs for downward actuation thereby, coil springs mounted between the guides and the dis'cs for raising the posts, and manually operable means for actuating the cams in unison.
